:) You have to be alert with the my butt extension installed though. Only a few days ago I answered a stack overflow question where I added a link with the word cloud in it. Unfortunately the extension changed the URL when I edited the raw text. Luckily I realised quickly when I double checked if the link worked and it 404ed...
I answered a question with the word cloud in it, and when I posted I saw 'butt' and thought I had accidentally copy/pasted wrong, so I Went back to edit, BUT THEN I SAW IT AGAIN and edited 3 more times before realizing that it just 'wasnt saving' because it was saving, I just had the extension on.
